UhllTED FEEDING" DEVICE FURTJUDLILNG- BADIATORS.

Application filed January 29, 1924; Serial No. 688,223, and in France February 27, 19%.

Feeders are already known, that is to say large containers mounted in the cooling water pipes of a thermal motor and ensuring the supply of water to these pipes and the radiators which are connected thereto. The steam formed in the pipes is drawn into the radiators, when the motor becomes abnormally heated collects in these feeders and is partially condensed therein by the external cooling action or can escape into the outer air.

The feeder arrangements hitherto known however do not afford a sufliciently intense cooling and do not permit of a sutliciently rapid condensation of the steam.

The present invention relates to a special arrangement of feeder which avoids the preceding disadvant ges. This arrangement is characterized substantially by a container of suitable surface and volume connected to the cooling water system of the motor this con tainer being combined with a sleeve for the admission of air to the carburettor, so that the cold air drawn into said sleeve ensures an intense cooling oi the elements or this container increasing consequently, the condensation oi": the steam which may collect in this container and ensures the heating up of the carburetter by the heating of the air admitted thereto.

farious arrangements according to thisinvention are shewn by way oi example in the accompanying drawings in which:

Figure 12 is a side elevational view or the oarburetter and air connection thereto from an auxiliary reservoir ofthe type illustrated in Figure 6.

The arrangement shewn in Figures 1 to 3 comprises a reservoir 1 and a sleeve 5 for admitting air to the carburetter.

The reservoir 1 is provided plug 2 and is connected by two pipes 3 to the water jacket of the motor. Battles lfixed to the interior of the reservoir, guide the currents of hot water arriving'lrom the motor.

The air admission sleeve 5 is surrounded by a jacket or casing 6 which thus forms around the periphery of this sleeve a free space 7 communicating freely on the one hand by the openings 8 with the lower part of the reservoir 1 and on the other hand rith the water aclrets by the connection ,9.

The pipes 10, of very elongated cross section (see Figure 3) and provided with coolgills 11, connect the upper part and the lower part of the free space 7 passing right The arrangement above described works in the following manner:

When the. motor becomes heated abnormally. certain quantity of cooling water vaporizes. The level of this water sinks gradually in the reservoir and when this reservoir is entirely empty, the level of the water drops below the air sleeve 5. At this moment the pipes 10 and the free space 7 be come completely filled with steam and are intensely cooled by the current of cold air drawn in along l l intothe air sleeve. They thus constitute a condenser of large cooling surface which ensures rapid condensation of the steam formed in the pipes.

This intense cooling action produced by this condenser counterbalances the abnormal heating of the'motor.

lVhile the motor is working normally, the hot water drawn in by the pump passes into the reservoir 1 by the pipes 8. These two currents of hot water are diverted d0wnwards by the bailies 4t, and passthrough the openings 8, then into the free space 7, through the pipes 10 and escape through the pipe 9.

The air drawn into the air sleeve 5 in the direction shewn by the straight arrows li with a filling iltl ll il illitplays over the lateral surfaces of the pipes 10 and the gills 11 fixed on these pipes.

This ensures, while the motor is running normally. both a certain cooling of the water which passes through the reservoir 1, which facilitates the work of the radiators, and a heating up of the air admitted to the carburetters and consequently the heating of the curburetters themselves.

The particular arrangement of the reservoir 1 relatively to the air sleeve v5, this reservoir being arranged above the air sleeve and the pipes 10. has the advantage that. when the motor is running normally, the pipes 10 are constantly filled with hot water and thus constantly ensure the heating" of the carburettor.

The arrangement shewn in Figures 1 to 3 has been described by way of example only and may compriseinnnerons modifications to which this invention extends.

In particular. instead of arranging the reservoir 1 above the air sleeve. the pipes 10 prolonging the lower part of this reservoir into the interior itself of the air sleeve. I may on the contrary arrange the reservoir below the air sleeve In this case, the pipes 10 prolong the upper part of the reservoir through the air sleeve 5.

The circulation of hot water in this arrangementis exactly similar to that in the arrangementshewn in Figures 1 to 3. This circulation of the water is indicated by the arrows in Figure 4.

As soon as the level of the water in consequence of excessive wear or heating of the motor, sinks in the pipes 10. these pipes. 1ntensely cooled by the air drawn into the sleeve 5, atonce act as a condenser and condense the steam which has collected in the apparatus.

These pipes continue also to heat up the air admitted to the carhuretter. by giving up to this air a fraction of the heat still contained in the hot water circulating in these pipes.

It has been supposed in the preceding examples (i. e. Figures 1 to 4) that the reservoir 1 is placed directly'around the air sleeve 5. I may obviouslyhowever. place this reservoir slightly above the air sleeve as shewn in Figure 5. this reservoir then communicating with the free space 7 by a pipe 40.

This arrangement works in exactly the same way as the preceding ones as soon as the level of the water sinks below the air sleeve 5, all the parts 10, 11 act as condensers according to the invention.

I may also as shewn in Figures 6 and 7 place the reservoir 1 inside the air sleeve, this reservoir and this air sleeve forming a single element.

In this case, the general outline of the reservoir 20 conforms to the general outline of the air sleeve. This reservoir is traversed along its axis by a pipe fit for the passage of air.

The air sleeve 5 is surrounded as formerly by a jacket or casing 6 forming around the periphery of this sleeve :1 free space 7 divided into two parts by longitudinal partitions 23. This free space communicates with the reservoir 20 by radial pipes 22 having The hot water coming from the motor by the two pipes 2-3 fills the upper part of the free space 7. passes through the radial pipes 22 into the central reservoir 20. passes on through another series of radial pipes 522, collects in the lower part of the free space 7 and flows through the pipe 9 into the cooling water pipes.

The air drawn in through the air sleeve 5 in the. direction indicated. by the arrows 14:, plays over the radial pipes then gills 24:. the outer walls of the central reservoir 20 and the walls of this reservoir which formed the central passage 21.

I thus obtain a eontini'lous heating of the air admitted to the mn'lnirettcr, and an intense condensation of the steam as soon as the level of the water sinks in the apparatus either in consequence of being used up or excessive heating of the motor.

In the arrangement above de cribed (see Figures 6 and 7) the central res rvoir 20. the radial pipes and the free space 7 constitute a series of elements communicating with each other and containing a large reserve of water which permits of the automatic replenishment of the losses in the pipes and radiators. Consequently in this arrangement the feeder, that is to say the container connected to the cooling water pipes of the motor and combined with the air sleeve, is in fact eonstitutech not only by the central reservoir 20, but also by all the preceding elements 90, 22, 7.

I can therefore constitute this feeder by dispensing with this central reservoir 20 and replacing it by bundles of tubes 30 having gills 31 (see Figures 8 and 9) passing from side to side of the air sleeve 5 and connecting together the upper and lower parts of the free space 7, separating the parti tions 23. on condition only of providing a sufficient number of these pipes and giving them a. suitable surface and volume. l

The hot water comes in from the motor at 3, fills the upper part of the free space 7. passes through the vertical pipes 30, fills the lower part of the free space 7 and re joins the general system of pipes by the connection 9.

The air circulates as before in the direc tion of the arrows 14.

This arrangement works as a condenser in a manner exactly similar to the arrangement shown in Figures 6 and 7. It will ill Lil)

be easily understood that by making the plpes 30 of suflicient (hamster and by providing a la ge number of these pipes inside the air sleeve 7, a feeder of large capacity will be obtained, containing a large quantity of water which automatically makes up the losses from the pipes and radiators.

The arrangement shown in Figure 9 also eiiiciently realises the essential characteristic of the invention, that is to say'the combination of a feeder and an air sleeve, the whole thus constituted acting as a condenser for steam.

l may obviously mount the above de scribed arrangements in numerous diii'erent ways on the general cooling pipes of the motor.

For example (Figure 10) an arrange ment 1, 2, 5, 10 according to that shown in Figures 1 to 3, may be realized on the one hand by the pipe 3 with the cooling jacket oi the motor, and on the other hand by the pipe 9, with a radiator 86, a rotary pump 37 draws in through the pipe 38 the cooled water into the radiator 36 and forces this water through the pipe 39 into the cooling jacket 35 of the motor.

ll may also place an arrangement 1, 2, 3, 5, 10 according to that shown in Figure 4, in the V formed by the cylinders (see Figure 11). This arrangement is connected by two pipes 3 to the cooling jackets 35, of these cylinders and by pipes 9 to the radiators 36.

The rotary pump 37 draws in by the pipes 38 the cooled water from the two radiators 36 and forces this water through the pipes 39 into the jacket-s 35 of the motors.

It will be seen that these various ways of mounting the whole constituted by the feeder and the air sleeve is arranged in order with respect to the rotary pump.
